Rocketmen: It Came From Uranus (yes, very clever) will be available from the American PSN Store on May 15th and will cost you $4.95. In exchange for that you receive three new levels of gameplay (if you can call it that) and five new weapons; three primary and two secondary. You must have Rocketmen: Axis of Evil in order to play It Came From Uranus and can play the new levels with your old character. As you can probably tell, we're not particularly fond of Rocketmen. You can find out why in our review.
